The above notwithstanding: BT ARE TOTAL CRAP. Sorry to the BT contingent on the list, but it has to be said. They are a load of total shysters, doing all sorts of monopolistic anti-competitive activities and cross-selling, while the spineless regulator is too thick to stop them. I'm not saying it's really BT's fault, as most corporations would probably do the same in their position.
When I worked for them selling call minder/call waiting I got told off because I did not try to sell to a senile old lady who could not understand the idea of an answerphone. I may have got at least �10 pounds for getting her a secondline.
Since then I have never advocated BT for anyone for anything, and i left to start my MSc 3 weeks later.
